Works fineBy Carmenon 7/21/2015

Like others said, the packet is awkward. I got around that by after cutting the top of the foil off, I pry open the top of the packet with sissors until it creates a point, then carefully tap the foil on the edge of the vial until all the powder falls in. I do, however, have a lot to say about the calcium test...

Hanna- do right to your customers and fix the packet!!!By Mrodon 6/27/2015

Hanna needs to redesign their packet design. If you like stress and frustration this is for you. Bottom line the packet design is a joke that outweighs anything else that is positive.

This is the first Phosphate test kit I have owned. Simple to use but as others have stated getting the powder out of the package is very tedious and not sure how accurate the reading is if the exact amount is not added...

Simple fast accurate testing method.By RAMONon 5/17/2015

I used this tester for the first time yesterday , and was surprised how easy and accurate it was. Testing water can already be a long dreaded task, but this hannah checker makes it a snap!, and its accuracy was great as well

Good InvestmentBy Pipe Doctoron 5/16/2015

This device takes the guesswork out of trying to associate a color shade with a number, however, the test cover does not fully close and they only give you 6-7 reagents for testing. So out of the box you (1) have to hold down the top cover when a vial is inside and (2) limited to only 6-7 tests before you need to buy more.

It seems to test well but the tester lid doesn't always snap closed properly. Also the packets of test powder are a little hard to get the powder out easily.

Good testerBy Russellon 5/4/2015

This tester is so much handier than the API test. It gives you an actual number instead of guessing at a color. It is also way more sensitive than the API tests. The downside is trying to get all of that reagent from the packet into that little vial without spilling it all over the place AND doing it within the time given. If it takes you too long, you have to start over. All around, a good device with a couple of quirks.

Too inaccurate for reef tanksBy Adamon 3/30/2015

Adam wouldn't recommend this product to a friend

This is a quality, easy to read test kit for phosphates, perfect for fish only or less-demanding reef tanks, but I wouldn't recommend buying this one for most reefers. The accuracy is only +/- 0.04 so if you're trying to maintain phosphates between 0.01 and 0.03 ppm then this kit is useless.

The ultra low range checker works on a parts per billion scale, which is probably more appropriate for the typical reef tank. It reads between 0 and 200 ppb, which is 0 and 0.2 ppm.

Oh, and I agree with everyone else who doesn't like the reagent packets.

Seriously? I bought this and used it about 2 or 3 times. The process of placing this tiny bag of powder into a tiny vial is ridiculous- regardless if it is accurate or not, it is poor product development. Don't believe me? Buy and try it. Not for me, next.
